Answer: C) Golgi apparatus and extracellular matrix

Explanation: The Golgi apparatus which is primarily site for complex polysaccahrides synthesis and the site where protein is processed and packaged for transport.

The extracellular matrix helps cells to stick together with each other. it also regulates a number of cell functions such as adhesion, migration and differentiation. It is formed by macromolecules such as protein and polysaccharides which are secreted by other cells.

Answer:

Golgi apparatus and extracellular matrix

Explanation:Golgi apparatus is the site of modification of synthesized protein transported by cisternae migration from the R.ER. Carbohydrate are either added or removed by the Golgi apparatus at this point. The extracellular matrix which contains storage of macromolecules provided the needed structural and support for the modification.

Therefore if the animal cell lacks ability to add polysaccharides to the protein then , the modification organelle-Golgi apparatus must be missing, and the biochemical support structure (extracellular matrix) for the modification must also be missing.
